Concept explainers
Where can you find chemicals?
a. In a hardware store
b. In a chemical stockroom
c. All around you and even inside of you
d. All of the above
Interpretation:
Amongst, the given options, identify the place where the chemicals are found.
Concept Introduction:
All things are composed of chemicals whether it is water, air, food, or everything we come across. Therefore, chemicals virtually make up everything that a person comes into contact with.
Answer to Problem 1SAQ
Correct answer: Option (d) is the correct answer.
Explanation of Solution
Reason for correct option:
Chemicals can be found in a hardware store. For example, aluminum wire and aluminum sheeting can be sold at a hardware store and these are made up of pure aluminum. In a chemical stockroom, all types of chemicals can be found as it contains a stock of chemicals. Chemicals compose ordinary things. Chemicals compose the air around us. Chemicals are even present within the human body such as hydrochloric acid found in our stomach is a chemical. Therefore, the chemical composition of human body is considered in terms of elements and compounds. Hence, all of the given statements are correct. Thus, option (d) is the correct option.
Reasons for incorrect options:
All the given options are correct. There is no incorrect option.
